5′′-(4-Chlorobenzylidene)-1′,1′′-dimethyl-3′-phenylacenaphthene-1-spiro-2′-pyrrolidine-3′-spiro-3′′-pyridine-2,4′′-dione

Abstract

In the title compound, C34H28Cl2N2O2, the five-membered pyrrolidine ring adopts an envelope conformation and the six-membered piperidinone ring is in a distorted half-chair conformation. The molecular structure shows three intramolecular C—H...O interactions and the crystal packing is stabilized through intermolecular C—H...O and C—H...π interactions.
